A kind of Anti-inclining ladder
technical fieldthe utility model belongs to the terraced technical field of electric equipment maintenance, is specifically related to a kind of Anti-inclining ladder.
background technologyat present, along with the development of society, the laying of power circuit is day by day perfect, and this allows the maintenance work in later stage also increase gradually.In rural area, just lay along eaves after electric wire gets off from main line bar, comprise under electricity meter box, electric brake etc. be all located at eaves, circuit is exposed to the weather aging unavoidably through for a long time always, use ladder when carrying out maintain and replace and climb up the maintenance climbed down, two supporting leg lower ends of ladder are on the ground, and upper end is leaned on the wall, because physical features complexity is various, people also will take instrument at both hands above, and ladder can slide along wall, and the safeguard procedures such as cannot to use of seat belts, there is serious potential safety hazard.
summary of the inventionthe purpose of this utility model solves prior art to there is the technical problem that ladder easily tilts, hazards are high, provides a kind of Anti-inclining ladder, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of Anti-inclining ladder of the utility model, it comprises flat ladder; Its main points are that the bottom dual-side of described flat terraced two legs is respectively equipped with the supporting leg connected by rotating shaft; Described supporting leg is provided with the bearing pin be connected with backstay one end; Described backstay is provided with chute; The lower end of described flat terraced two legs is respectively equipped with the alignment pin through backstay chute, and described alignment pin is slidably connected by the other end of nut and backstay.
The utility model structure is simple, easy to use, the basis of original flat ladder has added two supporting legs, can in four legs supports on the ground, adhesive power is stronger, and supporting leg spacing is adjustable, use more safe and reliable, solve prior art and there is the technical problem that ladder easily tilts, hazards are high.
accompanying drawing explanationaccompanying drawing is the utility model structural representation.

detailed description of the inventionwith reference to accompanying drawing, a kind of Anti-inclining ladder of the utility model, it comprises flat ladder 1; Its main points are that the bottom dual-side of described flat terraced two legs is respectively equipped with the supporting leg 3 connected by rotating shaft 2; Described supporting leg 3 is provided with the bearing pin 4 be connected with backstay 5 one end; Described backstay 5 is provided with chute 8; The lower end of described flat terraced two legs is respectively equipped with the alignment pin 6 through backstay chute, and described alignment pin 6 is slidably connected by the other end of nut 7 with backstay 5.
During use, unclamped by nut 7 of the present utility model, needing the place of work to be erected by ladder, select the angle be applicable to, make two legs and two whole adherence grounds of supporting leg of flat ladder, after stable, fastening nut, staff can ascending stair operation.
The distance of the flat ladder bottom of the utility model rotating shaft distance is 80-100 cm, and the distance of alignment pin distance ladder base is 40-50 cm, and a leg length is 120-180 cm.
